My wife has a Torch and wants to buy a PlayBook; but we don't know how to use the phone as a WiFi hotspot or at least connect them with an USB cable and tether it.
Re: How to use my Torch as a WiFi hotspot/tethering
To add to what Dubdub says above, the Bridge is super simple to set up, and will allow browsing using the BlackBerry handset's data connection. You can also tether, but that may not be necesaary, if the Bridge is adequate.
The PlayBook user manual is available at blackberry.com. Get that and read it first. Then browse the forums and read the issues some people are having. But read the manual first, and you'll understand what is being discussed. Posted via BlackBerryForums.com Mobile
